The National Eligibility cum Entrance Test (NEET) is a standardized test for students who wish to pursue undergraduate medical courses (MBBS, BDS) and dental courses (BDS) in India. The National Testing Agency (NTA) conducts the exam once a year.
The NEET syllabus 2024 is based on the 11th and 12th-grade NCERT curriculum of Physics, Chemistry, and Biology. The syllabus is divided into three sections: Physics, Chemistry, and Biology. Each section has a weightage of 180 marks.
NEET Syllabus 2024 Revised by NTA
The NEET syllabus 2024 has been revised slightly from the previous year’s syllabus. Some of the topics that have been removed from the syllabus include digestion and absorption in Biology, and some parts of electrostatics and optics in Physics.
It is important to note that the NEET syllabus is a guideline and not an exhaustive list of all the topics that may be covered in the exam. Students should also be familiar with the latest NCERT textbooks, as these are the main source of questions for the NEET exam.
